Specific to healthcare and the privacy issues associated with it, I am looking for an app that can notify a therapist that a patient has arrived for an appointment, has canceled or will be delayed. Ideally, there would be a smartphone app for therapists and a web front end for the receptionist to use to send out pre-set messages like "Patient has arrived." No protected health information will be transmitted, just generic notifications for "patient." I want to avoid using SMS if I can. Does anyone have experience with any notification systems like this? I am just dealing with a single receptionist and a group of 6 therapists. Any inexpensive and proven solution is welcome.
